Understanding the Problem
To solve the expression Z/3 - 5/4, we need to find a common denominator and then perform the subtraction.
Step 1: Identify the Denominators
- The denominators are 3 and 4.
- The least common multiple (LCM) of 3 and 4 is 12.
Step 2: Convert Each Fraction
- Convert Z/3 to a fraction with a denominator of 12:
- Z/3 = (Z * 4)/(3 * 4) = 4Z/12
- Convert 5/4 to a fraction with a denominator of 12:
- 5/4 = (5 * 3)/(4 * 3) = 15/12
Step 3: Subtract the Two Fractions
- Now we can rewrite the expression as:
- 4Z/12 - 15/12
- Since the denominators are the same, we can subtract the numerators:
- (4Z - 15)/12
Final Answer
- The simplified form of the expression is:
- (4Z - 15)/12
Now, you have the answer to the expression Z/3 - 5/4! This can be further simplified or evaluated depending on the value of Z if provided.
